Translation of "The rooster and the pearl" (Fables)

A young rooster was looking for food in the manure when he found a pearl. "What a fine thing you are," he exclaimed, "and in what an unfortunate situation! If a person longing to possess something of such value had found you, you would have been restored to your original splendour. Yet it is I who have found you, when I would have much preferred to find some food instead. So this isn't going to do you any good, and it doesn't do me any good either!"
